Answer:
The total contraction of the bar is 1.228 mm
Explanation:
The parameters given are;
Length of aluminium bar = 600 mm
Diameter of aluminium bar = 40 mm
Diameter of hole in aluminium bar = 30 mm
Length of hole = 100 mm
Modulus of elasticity of aluminium = 85 GN/m²
Applied compressive load = 180 kN
Where:
δ = Total contraction of the bar
A₁ for the hole section =
A₂ for the solid section =
L₁ = 100 mm
L₂ = 600 - 100 = 500 mm
The total contraction of the bar = 1.228 mm.
Answer:
Heat generation per unit volume is 45 KW.
Explanation:
Given that
Thickness of wall = 6 cm
Temperature distribution
-----1
K= 15 W/m.k
As we know that at steady state condition
-----2
Where q is the heat generation per unit volume.
So from equation 1
Now from equation 2
So q= 45 KW
So heat generation per unit volume is 45 KW.
